Functional analysis of OsAPX2 fractions. The relative APX (a) and molecular chaperone (b) activities of the four OsAPX2 protein fractions were compared with those of total protein (○) and no protein (●). The OsAPX2 proteins were separated into four fractions corresponding to the major dimeric form F4 (□), the LMW forms F2 (Δ) and F3 (■), and the HMW complexes F1 (▼). Molecular chaperone activity was evaluated using a 1:1 molar ratio of MDH and OsAPX2. The data are expressed as means of at least three independent experiments.
